I was playing Starmade, building myself a nice 2k-mass ship in singleplayer, and I just got done building the last weapon array (a 4-group missile-beam array; i knew it would be broken there due to the beam bug not getting fixed for multi-grouped missiles with beam slaves but i had it on anyway for when the next update comes out so i could immediately use it), and when I went to test the weapon array on a prop I made, my ship deleted itself the instant I pressed the mouse down to fire! I have no idea how this could happen, but right after that happened, StarMade crashed!

OK, so I just did some more testing of this bug and it happened to me again. I got kicked out of my ship when I fired the lockon missiles while flying, with my targeting reticle focused on another object. My ship disappeared the instant I fired, and the game crashed a few seconds later.
